Abstract

A new mesoporous base catalyst abbreviated as Meso-MC was synthesized by incorporating cerium and manganese oxides (MnOX/CeO2) into hexagonal mesoporous silica (HMS). The physicochemical properties of the catalyst were characterized by means of N2 adsorption, low and wide-angle X-ray diffraction, transmission electron microscopy, and FTIR spectroscopy. The catalytic activity of Meso-MC in the ketonization of various carboxylic acids was evaluated and compared with unsupported MnO X/CeO2 in a fixed-bed reactor at atmospheric pressure. Meso-MC is more active than the unsupported MnOX/CeO2 because of higher surface area, higher dispersion, and greater homogeneity of the MnOX/CeO2 mixture in HMS. Spectroscopic studies reveal that some large particles of MnOX/CeO2 are dispersed onto the surface of HMS while others are embedded into HMS mesoporous.
